## Discrepancy

CAPTAIN REPORTED THAT DURING TAXING TO PLATFORM, THE ELEC LIGHT TURNED ON. MAINTENANCE PERSONNEL PERFORMED ELECTRIC SYSTEM AUTO TEST IAW FIM 24-31 TASK 801 PROCEDURE, DETECTING THE STATIC INVERTER WITH FAILURE; SO THE STATIC INVERTER WAS REPLACED IAW AMM 24-34-21, TESTED CORRECT. AT GDL, DURING OVERNIGHT CHECK AND AS A PRECAUTIONARY ACTION, THE MAIN BATTERY WAS REPLACED IAW AMM 24-34-21-000-801/-400-801, TESTED CORRECT.
